A Data Manipulation Model: An Extension of the Alpha Expression
Summary: Extends the Alpha expression (relational calculus plus target list) with heterogeneous value-set operators, including aggregates, overcoming relational algebra/calculus limitations. Introduces imaginary tuples to concisely specify and efficiently implement traditional data-processing applications. (summarized by gpt-5.6-luna on Jul 24 2026)
